In a connector assembly including a pair of first and second connector housings, first and second adjacent connector housing units constituting of the first connector housing are coupled so as to be slidable in a fitting direction. A resilient securing arm is formed on an opposite wall of the first connector housing unit, a provisional securing piece is formed on another opposite wall of the second connector housing unit, and a protrusion for releasing provisional securing is formed on a fitting plane of the second connector housing. The resilient securing arm is abutted on said provisional securing piece to secure the first connector housing unit to the second connector housing unit provisionally in a state where the former is ahead of the latter. After the first connector housing unit is mated with the second connector housing, the protrusion is hit on the provisional securing piece so that provisional securing of the first and second connector housing units is released; and thereafter, the second connector housing unit is mated with the second connector housing.
